The Collected Letters, Volume 28

Sir—I myself hear nothing practical as yet about that cheap edition of my Book; and am inclined to think it may still be a year
or two before any such edition actually see the light. This is all the intelligence I can send you on that subject.

As you seem to be a studious enquiring man, I will recommend you to read well what good Books you have at command, and to reckon always that reading well is greatly more important than reading much. Not to say that the best wisdom, for every man, does not lie in Books at all, but in what conclusions he himself can form,
and what just insight arrive at, from all manner of suggestions and helps, whereof Books are but one sort.
